Calculate Power Requirements for a PTX10004 Router

Use the information in this topic to calculate power requirements of your PTX10004 configuration and
the number of power supplies required for different PTX10004 router configurations.
CAUTION:
recommend that you maintain n +1 power supplies in your router at all times. Replace
failed power supplies immediately to prevent unexpected failures.
If a new line card is installed in an operational router, power management does not
power on the line card if the increased power demand exceeds the total available
power, including redundant power. If redundant power is used to power on the line
card, a minor alarm is raised, which becomes a major alarm if the condition is not
corrected.
NOTE: The calculations in this topic represent the maximum power requirements that you need
to budget for your PTX10004 router configuration. The actual power consumption of your router
will be less than the calculated results shown here and will vary based on the hardware and
software configuration of your router, the amount of traffic passing through the line cards, and
environmental variables such as room temperature.
